Pump performance can be shown graphically as head or pressure against flow rate
? The rotodynamic pump has a curve where the head falls gradually at a steeper rate as flow increases.
? However, for a PD pump, the flow is almost constant whatever the head.
Nowdays I read some article in PDCA,HACCP, SIX SIGMA,FISH BONE,..
